The regression suite that never goes stale.

Most functional test suites start strong and decay fast. A selector changes, a test goes red, and someone has to stop what they're doing to figure out whether the product broke or the test did. Multiply that by every sprint and the suite becomes something people route around instead of trust. Teams end up in one of two places: a flaky suite nobody fully believes, or a backlog of manual regression checks waiting on a QA hire that hasn't been approved yet.

Once a flow is authored, it doesn't need AI to prove it still works. Donobu supports a DETERMINISTIC run mode that replays a test without further AI inference, so your CI pipeline stays fast and predictable instead of depending on a model call for every check. Set DONOBU_RUN_ID once in a CI step and every flow from that run, across parallel shards and workers, groups into a single identifiable test run instead of a scatter of timestamps you have to piece together by hand.

As your suite grows, organize it the way your team actually works: group tests into named suites, tag them, and search or filter reports by tag, failure mode, or triage status. It's a test suite built to be maintained easily, not just generated.

Every test Donobu writes is native Playwright in TypeScript, with Donobu extensions, checked into your repo like any other code you own. Donobu runs local-first, on your machine or in your VPC, so your product and data never leave your environment. There's no proprietary test format to learn: the exported tests read like any Playwright spec, and the Donobu extensions are the parts that add self-healing and semantic assertions on top. You also bring your own model: Donobu works with Claude, Gemini, and OpenAI models, and your API keys stay local. If you ever decide Donobu isn't for you, you keep a working test suite, not a subscription with nothing to show for it.
